Question

How is this A? Or is it wrong? This is polynomials

Answer 1

D

Explanation:

The volume for a rectangular prism is given by the formula:

`V=lwh`

The length is 2h, the width is 9-h, and the height is h. So:

`V=2h(h)(9-h)`

Multiply the first two terms:

`V=2h^2(9-h)`

Distribute:

`V=18h^2-2h^3`

Our answer is D.

I hope this helps!
